2 Claims.

The present invention relates to improvements in the construction and relative arrangement of parts in, and an improved method of constructing the spout-assembly for a general-purpose 5 hand-oiler.

One object of this invention is to provide, for a general-purpose hand-oiler, an improved construction and arrangement of parts'in the spoutassembly whereby the said spout-assembly is rendered surpassingly sturdy, durable and shock-resistant.

Another object of the invention is to provide a superior spout-assembly, for an oiler, comprising a minimum number of parts of simple form which are readily constructed and assembled by means of a relatively-small number of operations performed thereon, and thus conduce to the economizing of time-, laborand material-costs in the quantity production of hand-oilers and render hand-oilers of high quality available to consumers in an inexpensive form.

Still another object of the invention is to provide an improved method of producing oilers of the foregoing character, according to which a loose assembly of parts of suitable forms are disposed in prearranged relation to each other prior to a cold-working operation performed thereon to convert the said parts into the rigidly-interlocked members of a unitary structure having exceeding compactness and strength.

With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all feahr tures in the said disclosure which are novel over the prior art.

In the accompanying drawings, in which two specific modes of carrying out the present invention are shown for illustrative purposes:

Fig. 1 is a view, partly in side elevation and partly in vertical section of one form of handoiler embodying the present invention;

Fig. 2 is an enlarged broken vertical axial sec stance, is shown in the form of a screw-cap for the oil-receptacle;

Fig. 7 is a view partly in side elevation and partly in section of the spout-retaining member prior to its consolidation with the spout-assembly;

Fig. 8 is an inverted perspective view of the same;

Fig. 9 is a view in vertical axial section of a spout-assembly according to a modified form of theinvention, the assembled parts thereof being shown in their relative arrangement prior to con- 'solidation into a unitary structure;

Fig. 10 is a similar view of the spout-assembly after the parts are consolidated into a unitary structure;

Fig. 11 is a bottom plan view of Fig. 10;

Fig. 12 is a perspective view of the spout shown in Figs. 9 and 10; and I Fig. 13 is a view partly in side elevation and 20 partly in vertical axial section of the spout-supporting base-member or oil-container screw-cap.

According to the embodied form of the invention shown in Figs. 1 to 8 inclusive, an oil-container of conventional form which is generally designated by the reference character 20, includes a bottom wall 2| which is usually made flexible to serve as an oil-pumping diaphragm; and a conical side Wall 22 which merges upwardly into a contracted neck-portion 23 and is provided at the top with an inturned flange 24 which serves the purpose of a gasket-seat. Immediately below the top-flange 24, the contracted neck 23 is provided with exterior screw-threads 25.

As shown particularly well in Figs. 2 and 3, the spout-assembly for the hand-oiler comprises a spout-supporting base-member generally designated by the reference character 26; a spout generally designated by the reference character 2?;

and a spout-retaining plate generally designated by the reference character 28.

As shown particularly well in Fig. 6, the spoutsupporting base-member 26, according to the embodied form of the invention shown on the drawings, is constructed in the form of a screw-cap provided with a connection-flange 29 comprising a threaded attachment-portion 35] and a gasketreceiving portion 3! which is preferably provided with serrations 32 to facilitate the rotation of said screw-cap.

The spout-supporting base-member or screwcap 26 is provided with an annular top wall generally designated by the reference character 33 which is provided at its inner periphery with a depending hub-like tubular flange 34. The said top wall comprises a flat outer marginal wallportion provided interiorly with an annular seat 36 for a spout-retaining member or plate to be hereinafter described; and an upwardly protuberant annular-portion 31 with which the said tubular hub-like flange 34 forms a circular shoulder or spout-seat 38 extending around a central aperture 39 for the reception of the spout 21 in the manner to be hereinafter more fully pointed out.

As shown particularly well in Fig. 5, the spout 2'! comprises a tapered elongated oil-discharging portion 40; a cylindrical terminal mounting-portion 4| at its lower end; and a protuberant bead 42 which intervenes between the said oil-discharging portion 40 and the mounting-portion 4| of the spout 21.

As shown particularly well in Fig. '7, the spoutretaining plate 28 comprises a downwardly-protuberant annular wall 43 having an outer peripheral edge 44 which is smaller in diameter than the inside diameter of the threaded attachment-portion 30 of the screw-cap 26 to permit its placement therein in engagement with the flat annular seat 36 on the inner surface of the marginal wallportion 35 of the top wall 33 and an inner hublike tubular flange 45 which is integrally formed with the said wall-portion 43 at and around a circular shoulder 46 which extends around a central aperture 41.

For the purpose of prearranging the foregoing parts in a loose assembly, preparatory to their consolidation under pressure into a unitary structure, the cylindrical terminal mounting-portion 4| at the bottomend of the spout 21 is inserted through the central aperture 39 formed in the top wall 33 of the screw-cap or spout-supporting base-member 26 until the protuberant bead 42 on the spout 21 is securely seated on the shoulder or seat 38. The downwardly-protuberant retaining-plate 23 is then positioned within the spoutsupporting base-member or screw-cap 26, as shown particularly well in Fig. 2, with its outer peripheral edge 44 in slidable engagement with the annular seat 36 extending around and within the outer marginal wall-portion 35 of the top wall 33.

With the parts thus prearranged, the spoutretaining plate 23 is pressed axially toward the top wall 33 of the screw-cap 26 to force the hublike flange 45 into juxtaposed relation to the hublike flange 34 on the annular top wall 33 and into telescopically-int-erfitted engagement with the cylindrical terminal mounting-portion 4| of the spout, as shown particularly well in Fig. 3.

During the compression of the said top wall and retaining-plate, the protuberant wall 43 of the retaining-plate is buckled and deformed to expand its outer periphery 44 into interlocking engagement with the inner wall 48 of the gasketreceiving portion 3| of the screw-cap. During this operation, the spout-retaining plate 28 is cold-worked to provide it with an outer marginal flange 49 which closely conforms to the marginal wall-portion 35 of the top wall 33. While these parts are in their relative positions described above, the lower end of the terminal-mounting portion of the spout is spun outwardly over the circular shoulder 36 on the retaining-plate 28 to form a locking-lip 50 which retains-the parts in permanently-set relation to each other as is shown particularly well in Fig. 3.

By an inspection of Figs. 1 and 3, it will be seen that the cylindrical terminal mountingportion 4| of thev tapered spout is encircledby designated by the reference character 58, comprises a flat annular wall-portion 59 and an upthe axially-spaced hub-like tubular flanges 34 and 45 of a circular wheel-like frame comprising the axially-bent oppositely-protuberant disklike members 31 and 43, which are locked together, against relative lateral-displacement, by 5 the cylindrical mounting-portion 4| of the spout during the consolidation of the several parts into a unitary spout-assembly structure. This wheellike unitary structure is reinforced circumferentially by a flat circular band comprising the 10 flat outer marginal-portion 35 of the top wall 33 and the marginal-flange 49 of the spout-retaining plate 28. The said flat circular band is disposed substantially in the medial transverse plane of the wheel-like frame, so that the pro- 15 tuberant walls 31 and 43 based thereon, and extending inwardly to and around the hub-like tubular flanges 34 and 45, provide a structure whereby the spout 40 will be braced and counterbraced in every direction above and below the common transverse plane of the said flat circumferential band.

By means of this construction, an exceedinglyrugged structure is formed from sheet-metal parts of small bulk and light construction to provide an inexpensive spout-assembly of high quality. When the spout-assembly is placed upon an oil-receptacle in the manner shown in Fig. 1, a circular gasket 5| is placed upon the inturned flange 24 and clamped thereto by the outer marginal flange 49 of the retaining-plate 43 when the screw-cap is threaded home on the oil-receptacle.

Figs, 9 to 13, inclusive, show another embodied form of the invention suitable for use on the oil-container 20 shown in Fig. 1.

The spout-assembly, according to this embodiment of the invention, comprises a spout-supporting base-member or screw-cap which is generally designated by the reference character 52; a spout which is generally designated by the reference character 53; and a spout-retaining plate which is generally designated by the reference character 54. The screw-cap 52 comprises a lower threaded connection-portion 55 of the circumferential Wall of said screw-cap and an upper gasket-receiving portion 56 which provides a circumferential recess 51 for a gasket (not shown). The top wall of screw-cap 52 which is generally wardly-protuberant annular wall-portion 6B which carries an upwardly-presented hub-like tubular flange 6| extending around a central aperture 62.

The spout-retaining plate 54, as shown particularly well in Fig. 9, comprises a downwardlyprotuberant annular wall 63 which has an outer peripheral edge 64 of suitable diameter to permit the said spout-retaining plate 54 to be introduced readily into the screw-cap and an inner peripheral hub-like tubular flange 65 which is also presented upwardly for a purpose now to be explained.

According to this embodiment of the invention, the prearranged loose assembly of the parts is built up by placing the spout-retaining plate 54 within the spout-supporting base-member or screw-cap 52 with the outer peripheral edge 64 of the said retaining-plate in slidable engagement with the inner surface of the marginal wall-portion 59 of the top wall 58 of the screwcap. While the spout-retaining plate 54 is thus held in position within the screw-cap 52, the tapered spout 53 is introduced, small end first,

through the apertures 66 and 62 until its upward movement is arrested by the said spout 53 coming into positive engagement with one or the other or both of the tubular flanges BI and 65.

As shown particularly well in Fig. 12, the tapered spout 53 is of substantially-uniform taper throughout its length and has an unbroken exterior surface which substantially conforms to the inner walls of the tubular flanges BI and 65. In consequence, when the prearranged looselyassembled parts shown in Fig. 9 are subjected to axial compression under suitable conditions,

, the spout 53 is forced upwardly through the tu- I Fig. 10.

During the continuance of this axial-compression operation, the downwardly-protuberant annular wall 63 is buckled in such a way as to form thereon a flat outer marginal flange 61 which is pressed into flatwise reinforcing engagement with the under surface of the flat annular wall-portion 59 of the top wall 58 of the screw-cap and peripherally interlocked with and at the inner surface of the gasket-receiving wallportion 56 of the said screw-cap.

As clearly shown in Fig. 10, the above-described axial compression of the prearranged loosely-associated parts shown in Fig. 9 serves to consolidate the said parts into. a unitary spout-structure extending around and including the bottom end of the tapered spout 53. The wheel-like frame thus formed, is substantially triangular in radial cross section and is circumferentially reinforced by a flat circular band comprising the flat annular Wall-portion 59 of the top wall 58 and the outer marginal flange 61 of the spout-retaining plate 54.

As shown particularly well in Fig. 10, the composite circumferential band comprising the marginal wall-portion 59 of the cap 52 and the outer marginal flange 61 of the spout-retaining plate 63 is disposed substantially in the medial transverse plane of the wheel-like frame so that the oppositely-protuberant disks BI] and 63 which constitute the upper and lower members of the said wheel-like frame, are directly interposed between the inner peripheral edges of the circumferential band and the tubular flanges GI and 55 respectively which are rigidly tied together by means of the terminal end-portion of the tapered-spout 53 at the bottom. In this embodied form of the invention, it is preferable to provide a soldered-joint 68 at one place only, namely, within the circular recess extending between the tubular flange and the bottom end of taperedspout 53. The joints between the spout and the tubular flange 6|, as well as that between the annular flange 61 and the inner surfaces of wallportions 52 and 59 of the cap, are readily made tight by a press-fit alone.

A spout-assembly constructed in the foregoing manner produces a unitary structure in which the spout is braced and counterbraced in every direction by the upper and lower tubular flanges 6i and 65 based upon and rigidly united by the spout itself.

A spout-assembly of this character is readily constructed of sheet-metal parts which are readily formed by a few and simple stamping operations and thereby shaped to permit of them being readily interlocked together by a cold-working operation which converts them into a unitary structure.

The invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming with the meaning and equivalency range of the appended claims are intended to be embraced therein.
